Spatial Patterning of Modular Gelatin‐Peroxide Microspheres in Melt‐Electrowritten Scaffolds Provides Controlled Oxygen Generation and Mitigates Hypoxia and Cytotoxicity

Advanced Healthcare Materials, EarlyView.
A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

Biofabrication of Endothelialized, Intrinsically Vascularized 3D‐Printed Recombinant Spider Silk Scaffolds

Advanced Healthcare Materials, EarlyView.
This study evaluates 3D‐printed recombinant spider silk hydrogel eADF4(C16)‐RGD in a rat AV loop model for tissue engineering. Constructs with T17b endothelial progenitor cells showed enhanced vascularization and biodegradation. Results highlight the importance of scaffold design and cellular integration in improving vascular density and overall ...

Speleotourism in Slovenia: balancing between mass tourism and geoheritage protection

Open Geosciences, 2018
Slovenia is considered as the cradle of karst geotourism as cave tourism started there as early as the Middle Ages. To date more than 12,000 caves were discovered from which 22 have the status of tourist caves.

Taming the Immiscibility of Gold, Iron, and Boron to Craft Chemodegradable Nanoparticles for Multimodal Imaging and Radiotherapy

Advanced Healthcare Materials, EarlyView.
Over half of cancer patients undergo radiotherapy. Laser ablation enabled the synthesis of immiscible Au‐Fe‐B nanoparticles designed as degradable bimodal radiosensitizers for X‐ray radiotherapy (XRT), boron neutron capture therapy (BNCT), and bimodal imaging for X‐ray computed tomography (CT) and magnetic resonance imaging (MRI). These nanosensitizers
